Recently, I have installed oracle 12c in my PC. And I am able to connect with the ANONYMOUS user and connection name ORCL. But I am not able to create any objects in database like tables creation, it's just showing the error message like- you don't have sufficient privileges.

Could you please help on this? How to start the work on oracle 12c database as I have worked on Oracle 11g with the SCOTT user and connection name ORCL.It was working fine. But SCOTT user is not present in 12c. Is there any other USER in 12c with the default tables like EMP table in 11g in the SCOTT USER schema?
